Hallo Jayne, welcome to the forum.
This is a bit of a puzzler
Your bird sounds like a strange hybrid of jay and hoopoe. Was it one of these...

Hoopoe is rare, but not impossible, given the time of year and your location. There have been several records in southern UK over the last couple of weeks, and given the current easterly winds, there might well be more to come.
